Braunstamos said the company works hard to get all the little details right. For instance, they craft fingernails and toenails from acrylic, the same material used in nail salons, so people can paint them.

"That's often important to women," he said.

Braunstamos admits that the realistic looking appendages don't function as well as prosthetics with built-in bionics, but the fingers are flexible enough for someone to play the piano. The artificial arms and feet can also perform basic tasks, he said.

Each prosthetic costs between $2,500 and $8,500, depending on the size and the level of customization. However, in Europe where most of them are sold, the majority of the cost is picked up by insurance, Braunstamos said.
